Interesting question, I wondered for a long time if the urban legend that sperm actually smooth the skin is real or not. Here's the thing: there's scientific bases that point in the affirmative direction.
There's a specialized organ inside the sperm cell called acrosome, it's a vesicle that contains a potent enzyme that basically makes a hole in whatever membrane it touches, it's designed to allow the head of the cell to enter the egg and initiate the DNA exchange.
Now, in theory that tiny amount of enzyme would destroy any skin too, so it would be the equivalent of a chemical peeling, but (and of course there's always a but), what I don't know if the sperm cell would release the contents of the acrosome on a epitelial cell, I believe it wouldn't or we wouldn't have balls, they would dissolve at the first batch of sperm we would produce.
So while I believe it's theoretically possible I think spraying girls is just a satisfactory practise that won't affect you or your partner/s.
